The ID transmitter contains the following functions: Incorporates the normal remote control buttons

Able to receive signal from transmitting vehicle antennas

Transmission of encrypted high frequency information Mechanical Keys

Signal encryption

The radio signals of the Remote Control are encryptedby means of a variable (rolling) code.

The rechargeable battery voltage is monitored independently by the Remote Control and

signaled to the CAS.

Up to four Remote Controls may be assigned to the vehicle for remote services (not

EWS, which may have up to 10).

Frequency range for U.S. changed from 315Mhz to 868.4Mhz.

The car can be started by means of the start/stop button in combination with the ignition switch

and key. This is the CAS & ZAS

This happens once access authorization has been confirmed (clearance signal from Car Access

System) and the brake pedal is depressed.

The start/stop button can also be used to switch off the engine or to select the various electrical

system statuses when the brake pedal is NOT depressed.

iDrive Application: Driving Area (Complete Coverage)

Comfort Area (Complete Coverage)

Frequently used basic functions such as lights, air conditioning/ heating

temperature, radio volume and rear window heater are controlled by means

of switches on the instrument panel.

In order to be able to make use this abundance of functions without having an

unmanageable array of controls and displays, the following concept has beendeveloped for the iDrive Comfort Area.

Access the iDrive Service Menu:1.) From the main screen, press and hold the iDrive

Controller knob for 10 seconds, until the knob graphic on

your screen changes.

2.) Turn the iDrive knob three clicks clockwise

3.) Turn the iDrive knob three clicks counterclockwise

4.) Turn the iDrive knob one click clockwise

5.) Turn the iDrive knob one click counterclockwise

6.) Turn the iDrive knob one click clockwise7.) Press the iDrive knob down and release

Automatic Heating and AC (IHKA):

Overview and Diagnostics

Output-controlled compressors with variable displacement

were developed for the purpose of adapting to different engine

speeds, ambient temperatures of interior temperatures selected

by the driver.

This adaptation is achieved by varying the angle of the

swash plate.

The IHKA is the master for controlling the A/C compressor.

Pressing the A/C button switches the air-conditioning system to ready

state, then enabling IHKA to transmit a speed increase request to the

DME (ECM).

The IHKA issues a command to the junction box to couple the connection.

When DME is in READY STATE, this allows to provide torque of > 20 Nm to the compressor, the DME (ECM) issues a release fora load connection of up to 30Nm.

The Junction Box Electronics (JBE) is extremely important to the

IHKA system, and is responsible for the following functions: Output signal for seat heating.

The signal path is: SZM => ribbon cable => IHKA => K-CAN=> JBE => SHM/SMFA

Rear window defogger.

The signal path is: IHKA => K-CAN => JBE (relay) => Rear window defogger

filters/grid

Blower motor operating voltage.

Refrigerant control valve (in compressor).The signal path is: IHKA => K-CAN => JBE => Operating voltage for valve

Condition Based Service:

To access the CBS date press the controller (CON), the

Settings menu will appear.

Turn the controller until Service is highlighted, then

press to activate the CBS menu.

NOTE!! The service operation display field always shows the

first five messages.

The display indicates the symbols for service information time,

distance and data information.

Any overdue service operations and symbols marked in RED in the

list are always at the top of the list of messages.

Turn the controller to select the required service operation and display

the selection by pressing the controller.

All fields can be reset using the service functions found in the

diagnosis program of appropriate software or scan tool.

The On-Board Monitor System was introduced as optional

equipment on the 1997 E38 and E39 models.

It was made standard on the E38 750iL for 1999 and standard

for all E38 in 2000.

In addition, the MARK1 Navigation system is incorporated into

the total scope of On-Board Monitor Control

The On-Board Monitor is essentially a control unit display.

The I-Bus is the communication line to the On-Board Monitor

Control Panel. Data communication takes place over the I-Busbetween the BMBT and the following modules:

IKE Telephone Handset Multi-Function Steering wheel

Radio Receiver Video Module Audio System Amplifier

The ARCNET: Attached - Resource - Computing - Network

The widescreen monitor replaces both the 5.5 version in the E38 and

E39. It also replaced the 5.0 units in the E53 and E46.

The widescreen display has a screen size of 6.5 with a 16:9 aspect

ratio.

The Mk-3 navigation system is a factory installed navigation system that replaces the previous Mk-2 version. The

purpose of the system remains the same as previous navigation systems:

There are two different hardware versions available dependent on the angle of installation

in the vehicle (horizontal or vertical). The Mk-3 is compatible with both board monitor or MIR display units.

MRS3 and MRS 4 system used Temic or Boschsensors. These sensors are not interchangeable and

must be matched with the airbag module in use. (i.e.

Bosch module uses Bosch side airbag sensor etc.)

This configuration consists of a ground connection

between the sensor and the module, the power sup-

ply comes from the module and the signal is trans-

posed over the power supply wire.

In the ISIS, the SIM is configured as byteflight master (bus

master). In principle, any satellite can be configured by

software as bus master. However, there may only be one

bus master in the system.

The SIM provides the synchronization pulses at intervals

of 250s. The alarm mode is transmitted across the width

of the sync. pulse. The duration of a sync. pulse in alarm

status is approx. 2s. Normally, the synchronization pulse

lasts approx. 3s.

Watchdog Function:The Intelligent Distributor allows the SIM to deactivate the power supply for individual satellites.

This possibility is used to implement a watchdog function. The relevant status telegram is used to monitor

the satellites.
